Slitting machine is equipment that can cut
different materials like plastic, paper or metal for various usages. For harder
materials, such as sheet metal, blades cannot be used. Instead a modified form
of shearing is used. Two cylindrical rolls with matching ribs and grooves are
used to cut a large roll into multiple narrower rolls. This slitter rewinder is
very economical yet precise; usually more precise than most other cutting
processes.
However, the occurrence of rough or
irregular edges known as burrs are commonplace on slit edges. Also, the
geometry of these rolls is determined by specific tolerances in addition to the
type of material and workpiece thickness. Continuous production processes are
available under quality strict control for more slitting products.
